Till Death Do Us Part ... it is missing a "Nothing of Interest" card?

Recommended Posts

Had a fantastic game of TDDUP today. It literally got down to the last possible investigator turn for them to win, and if they did not win, I (as the Keeper), was poised to win decisively instead.

But, when I seeded the board with cards, I was left with one room without a card for the investigators to explore. So I dropped in a "Nothing of Interest" from my other available supply. Is this a known issue?

The clue choices I made were, 1A, 2A, 3A, 4B, and 5A. With those choices made, and following the published list of room seeding, is there a missing NoI card? Or, did I do something wrong in my set-up?
